Efficiency improvement of a tidal current turbine utilizing a larger area of channel

KP Kim, MR Ahmed, YH Lee – Renewable Energy, December 2012

► Two cases of a single turbine in a channel and a number of turbines are simulated. ► In the case of a single turbine the velocity of water entering the turbine is small. ► The velocity of water increases for the case of multiple turbines. ► The power output and coefficient of power increase significantly for this case.
